2 days ago we had a powersurge and no electricity for 1 hour. After the power came back i turned on my server only to notice that i needed to run manual fsck_ffs for wd4. Being very busy in rl i shut off the power.

Now i got a little time over so i started the server, entered shell and tried
disklabel -p wd4
and according to disklabel there is no partitions at all, luckily this wasnt very important data but still, i havent "lost" data like that, might have been a few blocks but this seems to be the mbr?

Is there some sort of way to possibly restore the mbr?
doing fsck wd4 i get
Cant open /dev/wd4a: device not configured
